D. SULLIVAN. EEED WATER HEATER.

Patented July 12, 1881.

UNITED STATES PATENT OFFICE.

DANIEL SULLIVAN, OF LINCOLN, RHODE ISLAND.

FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 244,088, dated July 12, 1881.

Application filed April 30, 1881. (No model.)

To all whom it may concern:

Be it known that I, DANIEL SULLIVAN, of Lincoln, in the county of Providence and State of Rhode Island, have invented certain improvements in the manner of heating water for locomotive-boilers previous to its introduction to the boiler, by the use of waste heat from the smoke-chambenand from other parts of the boiler, of which the following is a specification.

My said invention relates to a feed-water heater for locomotive-boilers 5 and it consists, in part, of the adaptation to this use of the watercoil steam-generator described in my application for a patent which was allowed on the 26th day of February, A. D. 1881, and which bears the serial number of 24,617, and, in part, of an addition thereto of a worm or spiral coil for further heating the water before its introduction to the boiler.

My said invention also relates to a fender, consisting of a cone-shaped projection from the front of the engine, which is intended to receive and break the shock of any collision likely to occur, and which, in connection with the adapted water-coil above mentioned, is designed to protect the boiler and to reduce the liability to danger from escaping steam and hot water, in case of accident or collision aforesaid, when the boiler is broken into because of its unguarded condition.

The accompanying drawing, hereby made part of this specification, is a vertical section, showing the location of the water-coil a, with its inlet-pipe c and outlet d, and also showing the worm or spiral coil 0 in its chamber f, opening directly out from the fire-box g. The broken lines t 1' indicate the necessary shortening of the drawing. The tubes of the boiler are seen at k k. The fender is shown at m m,

and the bolts or screws by which it is fastened are seen at n n.

The object.of my said invention is, first, to utilize the waste or escaping heat in the smokechamber and from other parts of the boiler for the purpose of introducing the water into the boiler already heated; secondly, to raise the temperature of the water still higher before it is discharged into the boiler by use of the worm or spiral coil e and, thirdly, to protect the water-coil and boiler by the use of the fender m.

The inlet-pipe 0 extends to the tank, and conducts the water along the side of the boiler to the water-coil in the smoke-chamber. The construction of this water-coil is substantially the same as described in my allowed application aforesaid. The coursing of the water through this coil of pipes while they are exposed to the heat within the smoke-chamber raises its temperature nearly or quite to the degree of heat in the chamber, and it becomes quite hot by the time it passes into the outlet d. In passing thence through the connectingpipes and spiral coil 0 the water becomes still further heated, and enters the boiler at or considerably above the boiling-point.

The conical shape and hollow interior of the fender m are thought to be the forms of construction most likely to parry and resist the concussion incident to a collision or accident in front of the engine, and the manner of its fastening to the front of the locomotive by means of the screws or bolts n it permits its removal from or its use with the engine or boiler whenever and as may be desired; and

this part of my said invention may be used with other locomotives than those using my feed-water heater aforesaid.

It may become necessary from time to time to have easy access to the parts a, d, and e for the purpose of repairs, cleaning, 860., and to provide for this is the object of the manhole seen at o 0. This extends from the parts aforesaid to the exterior of the front of the locomotive, and is then covered by the manhole plate 8; and thus, upon the removal of said man-hole plate, entrance may be had to the several parts mentioned for all necessary purposes.

What I claim as my invention, and desire to secure by Letters Patent, is-

I. In combination with a locomotive-boiler, the fender an, arranged as shown, for the purpose of protecting the forward end of a boiler, and to reduce the danger from escaping steam and water in cases of accident by collision or otherwise, substantially as described.

2. In a feed-Water heater for locomotivethe parts a, d, and e, man-hole 0, and man-hole boilers, the combination of the man-hole 0 plate 8, all arranged in the manner shown, and and man-hole plate s with the parts a, d, and for the purposes described.

e, all in the manner and for the purposes sub- DANIEL SULLIVAN.

5 stantially as shown and described. Witnesses:

3. The combination, in a feed-water heater THos. P. BARNEFIELD, for locomotive-boilers, of the fender m, with S. GLOVER BENEDICT.
